I've come across the idea of emergence before. It's kind of tangential to one of the anthropic principles for me, ie. that we are meant to be here, and that consciousness was built in -- that the emergence is inevitable.
I still can't find the quite model or analogy for this. The computer model doesn't work for me. Although the "bootstrapping" idea seems to have some possible applications. It is almost like there is code, that wrote code, and when certain code is opened there is other code in there, and something somewhere knows how to read some code. But the conditions have to be correct too.
Then again,it is possible consciousness isn't emergent. But primary.
